CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent N0. 641,? '7 3, dated January 23, 1900.

Application filed May 13, 1899.

To all whom it may concern.-

Be it known that I, HENRY HOESOI-IEN, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain useful Improvements in Oentrifugals; and I do'hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speci fication.

This invention relates to an improvement in centrifugals.

The object of my invention is to provide a centrifugal machine, by means of whichfluids of various weights and densities may be separated and by means ofwhich solids and suspensions in liquids may be removed.

In the accompanying drawings I have shown in Figure 1 a centrifugal machine embodying my invention, with portions broken away. Fig. 2 shows a top view of the centrifugal proper, while Fig. 3 shows the position of the scoops used in agitating the material as it clings to the pan.

My invention embodies,essentially,suitable supporting-frame comprising the bottom D and the bars B and O. Extending from the bottom D and working within the upper bar 0 is a shaft S, and this shaft S is provided below with a suitable pulley N, adapted to receive a belt to drive the same. Secured to this shaft S is the centrifugal proper, compris ing an open-ended pan in the shape of two truncated cones united at their bases by means of the diaphragm R, as is clearly shown in Fig. 2. It will be noted, however, that this diaphragm is not exactly midway between the two cone-sections, but extends upward a suitable distance, so that the lower portion or division of the centrifugal is provided with a portion bulging outward from the bottom, as willbeunderstoodin referringto the drawings. This diaphragm R is provided centrally with a plurality of openings 6 and g, and has socured to it the upwardly-extending and inclined flanges E and F, which flanges are in the form of rings, as is shown in Fig. 2, below which are positioned the openings 6 and g. Extending from this diaphragm R is further a disk f,provided with an upwardly-extending 'edge,as is shown in Figs.1 and 2.

Serial No. 716,739. (No model.)

edge 5 This disk does not extend quite beyond the outer series of openings g. A downwardly-extending open-ended hood is further positioned or secured to this diaphragm R and entirely encompasses all of the openings 6 within the upper diaphragm and the openings g. This diaphragm Ris further provided with a plurality of openings (1 near its outer From this it will be seen that my centrifugal proper comprises an open-ended bulging pan, the openings of which are of a diameter lessthan the greatest diameter of the pan and which near the bulging portion is provided with a perforated diaphragm, which perforations are disposed in rings, each separate system of perforations being surrounded above by an upwardly-extending flange, while extending from the diaphragm down ward is a disk in the form of a table which is surrounded by a suitable hood.

Surrounding the shaft S and resting upon the pulley M is a sleeve L, from which sleeve L extend two arms, one of them being removed to show the proper construction in Fig. 1, while both arms are shown in Fig. 3. These arms J are provided with scoops H H, which are adapted to work against the inner surface of the lower section of my centrifugal and embody the upper scooping-blade H H proper and a series of lower blade-sections 1 2 3 4, &c., which are divided by suitable openings. These scoops may be plow-shaped, so that the material may be turned over. These larger scoops H H work within the lower portion of the centrifugal and, it will also be noticed, come in contact with the bottom of the diaphragm R immediately below the opening (1, as is shown. These scoops H H are revolved by the sleeve L. Extending from the sleeve L is a second system of scoops I, identical in construction with the scoops H H, but simply smaller, which work within the hood h, touching the top of the diaphragm R immediately below the openings 9, so that any material clinging within the lowerfportion of the centrifugal or within the hood 'H will be agitated and finally removed by means of these scoops H and I.

Entering the inner ring division F of my centrifugal from above is an ordinary supplypipe at, through which the oil, water, or mineral substances to be filtered or separated escape. Near the upper edge of the ring-sections formed by means of the ring E and the upper edge G of my centrifugal proper are the two escape-pipes b and c, which are held by means of suitable supports 3 and 4:.

Surrounding the lower open end of my centrifugal A is a suitable casing 0, within which casing is a chamber P, preferably sloping, into which material empties that escapes out of the lower open end of my centrifugal proper.

The operation of my device would be as follows: The shaft S and sleeve L are revolved, preferably, in the same directions at very high, but variable, speeds, so that while the centrifugal A is revolved at a very high speed the scoops II and I follow the same at a preferably reduced speed. If desired, the scoops may be revolved at a higher speed than the centrifugal. The material to be separated enters the centrifugal, while the same is in motion, through the pipe (L. It is then deposited upon the perforated diaphragm within the ring F. Here the heavier particles gravitate outward, partly finding an exit downward through the openings 6, while the lighter material washes upward over the ring F into the second annular compartment, formed by means of the ringE,where the material is again separated, the lighter material at the same time working inward and upward until it escapes over the upper edge of the ring E, while the heavier particles again gravitate outward to escape through the openings g. All of the heavier material that gravitates through the openings 6 is deflected from the tablef, while also a part of the heavier particles collected within the annular compartment formed by the ring E is also deflected from this table f. The remainder is whirled outward, lodging against the inner surface of the hood h. The lighter material as the centrifugal revolved would find an escape through the pipe 1), while what did not escape through this pipe would gradually wash over the ring E and enter the third chamber formed by means of the shell or casing G of the centrifugal proper. Here the lighter stuff would be again whirled inward and upward, while the heavier would again gravitate outward, escaping through the openings d and emptying through the pipe c,-up which the material would be shot as the centrifugal rotates toward the open ends of these tubes 1) and c. The heavier particles working through the perforations g and e and over the recurved edge of the table f would strike against the hood h and impinge themselves against this hood to remain stationary and revolve with this hood if it were not for the scoops I, which follow the hood H, and remove the collected material from the hood in the manner of a plowin that the material is successively turned over, and as the scoops are curved downward, as will be noticed in referring to Fig. 3, the material'is gradually fed toward the lower end of the hood H to empty through the same by means of these scoops I. tion to the material that escaped through the openings d, which would also lodge against the centrifugal, and a greater portion thereof would most likely cling to the same if it were not removed by means of the scoops II II. In order not to remove this material too rapidly, I divide the scoops near the lower ends, as is shown in Fig. 3, into different sections, so that what would escape being agitated between the openingssay 1 and 3will be removed by the projections 8 upon the opposite side, while the material that would not be removed because of the opening between the portions 5 and 7 would be removed by the portion 5 of the blade opposite. In this way the material is thoroughly worked to permit a fine separation. From this it will be seen that my centrifugal is so arranged that the lightersubstances are successively treated within the upper portion of my centrifugal, the heavier moving outward and downward and finally escaping out of the lower end of the centrifugal.

By this arrangement of instrumentalities I find that drinkingwater such as is taken from murky rivers can be nicely clarified in that the crystal pure water may finally be drawn off through the tube 0, while the sediment is removed by means of the scoops H H through the lower end. So, also, heavier oil may be separated from the lighter, as can also solids in suspension in fluids.

Having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent, is
